In supersonic planes the paasengers will walk like other planes?

Yes, you could walk about on Concorde, but there was not a lot of room to do so, the aisle was very narrow and the roof fairly low.

The biggest room issue was the toilets, quite seriously, a man had to decide just what he was going to do, because if you changed your mind when you got in there, there was really very little room to turn round!

Interesting fact however, because Concorde stretched about two feet with expansion as the aircraft heated up by air friction, there was about two inches more elbow room in the toilets when the aircraft was at Mach 2 than when it was on the ground.

Yes, the biggest limitation was the size of the plane. The Concorde was not very roomy. I've been in one at the Seattle Museum of Flight, and standing upright my head was brushing the cabin ceiling.

Passengers don't walk on supersonic airliners. They are conveyed from one spot to another on sedan chairs carried by flight attendants.
